Description
The present invention relates to a polymer synthetic resin composition and automobile interior and exterior materials using the same, and more particularly, by surface treatment of glass bubbles using fluorine treatment, and then mixing them with a polymer resin matrix, thereby polymerizing a polymer resin composition having uniform weight and physical properties. And it relates to the interior and exterior of the car using the same.
In recent years, fuel efficiency improvement technology for energy saving has become an important factor in determining the competitiveness of automobile companies, and research on vehicle weight reduction for this purpose is being actively conducted. Among polymer synthetic resins for vehicle weight reduction, in particular, glass bubble composite lightweight resins have improved scratch resistance compared to general mass production resins, which can be expected to eliminate the painting process of products, and release various VOCs (volatile organic compounds). It is getting the spotlight as an eco-friendly material that can prevent it.
GLASS BUBBLE is a type of 3D microsphere-filled filler with a hollow hollow structure.It is a plasticizer for PVC coating, epoxy structure form, It is widely used for weight reduction of parts through partial replacement of heavy fillers such as talc and glass fibers used in sheet molding compound (SMC), bulk molding compound (BMC), and reaction injection molding (RIM).
However, in the production of such a polymer synthetic resin containing glass bubbles, conventionally due to the aggregation of the glass bubble added at the melting point of the resin during the injection, the physical properties and lightening effect of the polymer synthetic resin and the product produced therefrom are generally uneven There was a problem.
Therefore, while maintaining the light weight and scratch resistance of the glass bubble, it is required to develop a technology for the polymer synthetic resin composition having a uniform light weight effect and physical properties as a whole and a product manufactured using the same.
The present invention is to solve the above problems, an object of the present invention is to provide a polymeric synthetic resin composition and a vehicle interior and exterior using the same while maintaining the light weight and scratch resistance of the glass bubble as a whole. .
In order to achieve the above object, the present invention provides a polymer synthetic resin composition comprising a fluorinated glass bubble. In addition, the present invention provides a vehicle interior and exterior materials made using the polymer synthetic resin composition.
The glass bubble is manufactured by a fluorine treatment step of directly surface-treating with high-purity fluorine gas. In the fluorine treatment step, the injection pressure of fluorine gas is preferably 0.4 MPa and the treatment time is 10 minutes. On the other hand, the glass bubble has a hollow microsphere form, is made of soda-lime or borosilicate glass, specific gravity is 0.1 ~ 1g / cc, crush strength is 200 ~ 20,000psi, size is 10 ~ 150㎛, polymer synthetic resin 100 It is preferable to add 0.1-50 weight part with respect to a weight part.
According to the present invention, it is possible to uniformize the degree of non-uniform weight reduction, which has been a conventional problem of the polymer synthetic resin composition to which glass bubbles are added for weight reduction, and further has an effect of obtaining a composition having improved resin properties.
In addition, there is an effect that can be used to produce a high-quality automotive interior and exterior with a uniform weight and physical properties as a whole using the polymer synthetic resin composition.

Hereinafter, embodiments of the present invention will be described. However, the scope of the present invention is not limited to the embodiment described below. Embodiments of the present invention are provided to more fully describe the present invention to those skilled in the art.
The present invention includes a fluorinated glass bubble in the polymer synthetic resin composition. The polymer synthetic resin composition according to the present invention is prepared including a polymer resin matrix and a glass bubble.
1 is a scanning electron microscope (SEM) photograph of a glass bubble used in the present invention. Glass bubbles may be present in a variety of colors, uses, specific gravity, crush strength and size, but the glass bubbles used in the present invention has a hollow microsphere form, it is preferable that the soda-lime or borosilicate glass composition. The color is preferably white or transparent in view of the milk canal. Otherwise, the manufacture and use of the product is limited to the color of the glass bubble. On the other hand, in order to effectively reduce the weight of the product, the specific gravity of the glass bubble is preferably 0.1 ~ 1g / cc. If the specific gravity is less than 0.1g / cc it is difficult to manufacture glass bubbles, if the specific gravity exceeds 1g it is not possible to achieve effective weight reduction of the product. In addition, in order to withstand the pressure of the injection machine during injection, the crush strength of the glass bubble is preferably 200 ~ 20,000psi. This is because it is difficult to withstand the pressure of the injection molding machine when the crush strength is less than 200 psi, and the problem of manufacturing cost increases when the crush strength is exceeded 20,000 psi. It is preferable that the size of the glass bubble is 10 ~ 150㎛ for an efficient process, in the embodiment of the present invention was used 3M glass bubble.
The polymer resin matrix used in the present invention can be used as long as the synthetic resin matrix generally used. For example, not only thermoplastic synthetic resins, such as a polypropylene resin, a polyethylene resin, an acrylonitrile butadiene styrene resin, an acetal resin, a nylon resin, a styrene resin, and a polycarbonate resin, but also thermosetting resins, such as an epoxy resin, a melamine resin, and a polyurethane resin Also available.
The present invention is characterized in that the surface of the glass bubble is directly treated with fluorine gas in order to eliminate aggregation of the glass bubble, which is the biggest disadvantage of the polymer resin composition including the conventional glass bubble. Fluorine gas treatment is relatively simple because the device is operated at low vacuum below room temperature, and the surface treatment device is relatively simple. Since it does not require a separate initiator and catalyst for initiating the surface treatment reaction, it is low in cost and various types of materials to be surface treated. They can be surface treated without affecting their internal properties. In addition, depending on the treatment conditions, various functionalities such as water repellency, hydrophilicity, adhesiveness, and functional group introduction can be imparted to the material surface. In the present invention, a fluorine gas treatment method (fluorine treatment step) usually used can be used.
As the fluorine gas used in the present invention, it is preferable to use fluorine (F 2 ) gas having a purity of about 99.8%, and purify the inside of the reactor using about 0.2% nitrogen gas before the fluorine gas reacts with the glass bubble. In addition, the reactor is preferably washed for 30 minutes after fluorination to protect the line and vessel of the reactor. As the material of the fluorine gas treatment device, it is preferable to use SUS-316 material which has corrosion resistance at room temperature with respect to fluorine gas.
The fluorine treatment process used in the present invention includes a fluorine gas injection pressure of 0.1 to 1 MPa and a surface treatment time of 0.1 to 1 hour. However, the fluorine gas injection pressure is preferably 0.1 to 1 MPa, and the surface treatment time is preferably 0.1 to 1 hour. The reason for limiting the fluorine treatment conditions as described above is that if the fluorine treatment of the glass bubble is made less, it is impossible to achieve the weight reduction effect of parts, which is one of the objects of the present invention. This can happen. The fluorine gas injection pressure and the surface treatment time correspond to suitable fluorine treatment conditions shown through repeated tests, and in particular, the optimum efficiency appeared when the fluorine gas injection pressure was 0.4 MPa and the surface treatment time was 10 minutes.
According to the fluorine treatment, various functional groups are introduced to the surface of the glass bubble to reduce the surface free energy between particles and reduce the binding force between particles, thereby preventing the aggregation of glass bubbles appearing near the melting point of the resin and the resulting nonuniformity of the resin. It can be improved.
FIG. 2 is a scanning electron microscope (SEM) photograph of the polymer synthetic resin containing the fluorinated glass bubble, and FIG. 3 is a scanning electron microscope (SEM) photograph of the polymer synthetic resin including the fluorinated glass bubble. 2 and 3, it can be seen that the polymer synthetic resin containing the fluorinated glass bubble is much less aggregation of the glass bubble than the polymer synthetic resin containing the non-fluorinated glass bubble.
Meanwhile, in the present invention, the fluorinated glass bubble is preferably added in an amount of 0.1 to 50 parts by weight based on 100 parts by weight of the polymer synthetic resin. When the glass bubble is added less than 0.1 parts by weight it is difficult to express the effect of the light weight in the prepared synthetic resin composition can not exhibit the effect of the glass bubble properly, when the glass bubble is added in excess of 50 parts by weight of the polymer synthetic resin composition and This is because not only the mechanical strength of the manufactured product is greatly reduced, but also a problem of cost increase.
By mixing the fluorinated glass bubble according to the present invention with a polymer resin matrix, a polymer synthetic resin composition having a uniform weight and physical properties can be prepared, and furthermore, excellent quality automotive interior materials, exterior materials, and cases of home appliances from the composition. Can manufacture household goods. For example, a photograph of an automobile interior material manufactured using the polymer synthetic resin composition according to the present invention is shown in FIG. 4.
Hereinafter, the present invention will be further described through Examples and Comparative Examples. However, the present invention is not limited by these examples.
< Example >
A pellet-shaped resin composition was prepared by mixing a fluorinated glass bubble (particle size: 10-150 μm) in a composite polypropylene resin (Tm: 135 ° C., density: 0.95 g / cm 3) in a weight ratio of 100: 3.
< Comparative example >
Under the same conditions as in the example, the pellets were prepared by mixing the non-fluorinated glass bubbles in a weight ratio of 100: 3.
After the compositions prepared in Examples and Comparative Examples were each injected into an injection molding machine and subjected to test injection using an auto parts mold, specific five points were determined to measure specific gravity and flexural strength (MPa) of each part. The results are shown in Table 1.
As a result summarized in Table 1, it can be seen that the specific gravity and flexural strength are the same or very small at any five points in the automobile parts manufactured using the composition including the fluorinated glass bubble as in the embodiment. On the other hand, in the case of automobile parts manufactured using a composition containing glass bubbles not treated with fluorine as in the comparative example, it can be seen that there are differences in specific gravity and flexural strength depending on the measuring point. From this it can be seen that the aggregation of the glass bubble (aggregation) is improved by the method according to the invention.
